DEFINITION

Classification: 42/2

Miscellaneous firearms adapted for loading at the breech. The subclasses under this title, except those of the spring-motor guns, and the grip-magazine pistols, are based on the movements of the breechblock or barrel in opening the breech. Features of magazine structure may be found in any

of the magazine subclasses.
